As if I haven’t touted the wonders of air frying enough, cooking this chicken in there also makes it extra juicy and crisp without any breading or oil.
Serve this chicken with your favorite veggie or carb-y side and have a healthy, fun meal that won’t break the budget or your weeknight routine. And, hey, look out for photos of French Onion Stuffed Chicken on dating apps.
An appetizing pic might not prove much but it has to show more than the ability to pose with someone else’s dog.

French Onion Stuffed Chicken Breast
Ingredients
- 1/2 teaspoon olive oil

Instructions

NOT-SO-PRO TIPS
Stuffing chicken is likely easier than you think! Take a sharp knife in one hand and use the other to press down on the top of the chicken. Start at the thickest end of the breast and slice inward about halfway down, using your top hand for control. Slice about 3/4 of the way through.
If you don’t have an air fryer, bake your stuffed chicken in a small casserole dish for about 18-20 minutes at 425 degrees until the thickest part of the breast is fully white and cooked when sliced or until a meat thermometer confirms that it is cooked through.
It is likely you won’t be able to stuff all of the onion into the actual chicken breast but that is ok as the rest will act as a sauce. Feel free to double/triple etc. this recipe if cooking for a larger crowd.
I like to err on the side of over-seasoning when making a simple chicken dish like this one. It helps make for an extra moist, flavorful chicken breast without increasing calories or fat.
